BN-OF PLANK (FIRE-RETARDING)

The fire-retarding covering BN-OF was developed as an alternative to conventional coverings, based on the well known Lichtgitter metal plank product BN-O. The planks have an outward edge to one underside edge achieving an approximate support area of 20mm, and both the short edges come with closed sides. This advanced product BN-OF is especially suitable as a covering for the oil collecting pans beneath transformer units.
